A Fish Habitat Classification Model For The Upper And Middle Sections Of The Bay Of Quinte, Lake Ontario, C. K. Minns, Andrea Bernard, C. N. Bakelaar, M. Ewaschuk

Marine & Environmental Sciences Faculty Reports

A fish habitat classification model was developed and applied to the upper and middle sections of the Bay of Quinte, Lake Ontario. Available habitat inventories were assembled in a GIS database, bringing bathymetric, shoreline, substrate, and vegetation data together in a series of layers. The classification model was developed in four steps. In the first step, the Defensible Methods (DM) model developed by Minns et al. (2000) was used to estimate suitability values in all habitat patches for a set of nine fish groups each with three life stages. The fish groups were formed from the assemblage of fish species …

Moving From Separate Subject To Interdisciplinary 1 Teaching: The Complexity Of Change In A Preservice Teacher K-1 Early Field Experience, Janet C. Richards, Kim T. Shea

The Qualitative Report

This phenomenological inquiry looked at 28 preservice teachers as they participated in a field-based curricula restructuring initiative that connected the disciplines of creative arts, science, and reading. The preservice teachers offered weekly interdisciplinary lessons to kindergarten and first grade students . A survey, teaching cases, and a group exit interview informed the study. Throughout most of the semester, the preservice teachers struggled with procedural and pedagogical content knowledge, concerns directly related to effective teaching. By the end of the semester, they felt comfortable teaching interdisciplinary lessons. Results suggest that preservice teacher curricular restructuring efforts are complex and that teacher educators …

Fractal Patterns Of Coral Communities: Evidence From Remote Sensing (Arabian Gulf, Dubai, U.A.E.), Samuel J. Purkis, Bernhard Riegl, Richard E. Dodge (Editor)

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

In this study, the spatial character of benthic communities is investigated in an Arabian Gulf shallow subtidal carbonate ramp setting, using IKONOS satellite imagery. The patchy distribution of three assemblages of live and dead corals on extensive (but also fragmented) hardground pavements was investigated using a variety of spatial statistics. It was found that the spatial expression of the benthic groups display characteristics that approximate to power-law distributions over several orders of magnitude to an extent that suggests fractal behaviour. Pronounced anisotropy was observed between the spatial patterns in the near-shore and off-shore region which is attributed to different mechanisms …

Application Of Paleoclimatology To Coral Reef Monitoring And Management, C. Mark Eakin, Peter K. Swart, Terrence M. Quinn, Kevin P. Helmle, Jennifer M. Smith, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The skeletons of reef-building corals are valuable archives of climatic and environmental information. Paleoclimatic data chiefly have been generated in areas most sensitive to global or regional climatic variability. However, these records also provide valuable information on anthropogenic influences – guidance of value to resource managers. NOAA’s Coral Reef Watch targets observations of current and past coral reef health in or near marine protected areas through satellites, in situ sensor platforms, and paleoclimatic analyses. Paleoclimatic data provide retrospective monitoring through multi-century environmental reconstructions that improve our understanding of past stress to coral reefs. Two sites in the Florida Keys National …

Growth And Survivorship Of Scleractinian Coral Transplants And The Effectiveness Of Plugging Core Holes In Transplant Donor Colonies, Elizabeth Glynn Fahy, Richard E. Dodge, Daniel P. Fahy, T. Patrick Quinn, David S. Gilliam, Richard E. Spieler

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Replicate scleractinian coral transplants were obtained from the species Meandrina meandrites and Montastrea cavernosa on a natural reef, off Dania Beach, Florida, using a hydraulic drill fitted with a 4 in. (~10 cm) core barrel. The transplants were fixed to Reef Ball™ substrates using an adhesive marine epoxy. Drill holes in the donor corals (core holes) were filled with concrete plugs. Control corals, of comparable size to both donor colonies and transplant corals, were monitored for comparison. Transplant corals, donor corals, and controls on the natural reef were monitored for growth and survivorship. Core holes were monitored for tissue regrowth …

Spatial Patterns In Arabian Gulf Coral Assemblages (Jebel Ali, Dubai, U.A.E.) In Response To Temperature-Forcing, Bernhard Riegl, Samuel J. Purkis, Kevin E. Kohler, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

We evaluated spatial and temporal patterns using maps from Ikonos satellite imagery in combination with 8 years of line transects and photosquares and the HadISST1 sea-surface temperature data set to explain why coral assemblages in the southern Arabian Gulf (Dubai) are impoverished and mostly do not build framework reefs. Analysis of archive sea surface temperature (SST) data confirms that the area is subjected to recurrent temperature anomalies. Frequencies of anomalies might suggest at least a partial link to the El Niño Southern Oscillation possibly via the Indian Ocean Zonal Mode. The dominant driver of local temperature was oscillations in the …

An Experimental Histopathological Rating Scale Of Sedimentation Stress In The Caribbean Coral Montastraea Cavernosa, Bernardo Vargas-Ángel, Bernhard Riegl, David S. Gilliam, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Colonies of Montastraea cavernosa were exposed to daily applications of approx. 200–225 mg cm– 2 sediments, during a four-week period, in order to investigate coral responses to increased sedimentation. Effects were assessed based on the histopathological condition of specimen tissues. Mild stress responses were noted as early as week one, including tissue swelling and polyp retraction, as well as changes in size and appearance of mucous secretory cells. As stress progressed, further inflammation of the mucous secretory cells was observed. Severe effects were observed in weeks 3 and 4, including atrophy of the outer epidermis, increased granularity and debris in …

Visual_Hea: Habitat Equivalency Analysis Software To Calculate Compensatory Restoration Following Natural Resource Injury, Kevin E. Kohler, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Habitat Equivalency Analysis (HEA) is a means to determine the amount of compensatory restoration required to provide services that are equivalent to the interim loss of natural resource services following an injury. HEA includes a discounting procedure to account for asset valuation in that the total asset value is equal to the discounted value of the future stream of all services from the natural resource or the compensatory resource. Discounting is used to include the relative valuation of loss and gain of ecological services of the resources over time. Visual_HEA is a computer program developed to calculate the amount of …

Coral Of Opportunity Survivorship And The Use Of Coral Nurseries In Coral Reef Restoration, Jamie A. Monty, David S. Gilliam, Kenneth Banks, David K. Stout, Richard E. Dodge

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Coral reef damage is unfortunately becoming a common occurrence off southeast Florida, U.S.A. Reattachment of the dislodged scleractinian corals usually initiates damage site restoration. Because mortality of dislodged colonies is typically high and natural recovery in southeast Florida is typically slow, transplantation of additional scleractinian corals into a damaged area has been used to accelerate reef recovery. Donor colonies available for transplantation have been grown in situ, grown in laboratories, and taken from nondamaged reef areas. An alternative source of donor colonies for transplantation into damaged sites is “corals of opportunity,” which we define as scleractinian corals that have been …

Implications Of Natural Variation Of Fish Assemblages To Coral Reef Management, Lance K. B. Jordan, Richard E. Spieler

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

In order to evaluate the impact of a planned beach renourishment project we obtained baseline data on hardbottom coral reef fish assemblages adjacent to the beach. During the summers of 2001 and 2003 we conducted 92 and 89 visual transect-counts, respectively, each 30x2x1m. Fish were recorded by species, abundance, and size class. Fish exhibited a 62.8% decrease in abundance between the 2001 and 2003 surveys. Juvenile Haemulon spp. (<5cm total length, TL) alone decreased 72.8% in abundance and, due to their predominance, primarily drove the decrease seen for total abundance. The second most abundant species Halichoeres bivittatus, also primarily juveniles (<5cm TL), contributed 8% of the total abundance and also showed a significant decrease between the 2001 and 2003 surveys. Even after removal of the two most abundant taxa, total abundance remained significantly lower the second survey year, suggesting the possibility of a community-wide decrease in abundance. However, the decrease between years was mainly due to a decrease in juveniles. When fish less than 5cm TL were removed from the dataset, no significant difference in abundance between years was detected. Species richness also declined significantly with fewer species noted in 2003 and eight fewer total species between years. Nonetheless, multivariate examination of assemblage structure did not indicate a difference between years. These results have important implications for determining potential anthropogenic change in fish assemblages (e.g. caused by beach renourishment).

A Catalog Of Edge-On Disk Galaxies: From Galaxies With A Bulge To Superthin Galaxies, Stefan Kautsch, E. K. Grebel, F. D. Barazza, J. S. Gallagher

Chemistry and Physics Faculty Articles

Spiral galaxies range from bulge-dominated early-type galaxies to late types with little or no bulge. Cosmological models do not predict the formation of disk-dominated, essentially bulgeless galaxies, yet these objects exist. A particularly striking and poorly understood example of bulgeless galaxies are flat or superthin galaxies with large axis ratios. We therefore embarked on a study aimed at a better understanding of these enigmatic objects, starting by compiling a statistically meaningful sample with well-defined properties. The disk axis ratios can be most easily measured when galaxies are seen edge-on. We used data from the Sloan Digital Sky Survey (SDSS) in …

Sponges Of Navassa, Janie L. Wulff, Timothy D. Swain

Marine & Environmental Sciences Faculty Reports

This photographic guide was compiled from data collected during the 2004 NOAA survey of the coral reefs of Navassa and does not represent a comprehensive list of all Porifera in Navassa. Specifically missing are taxa that inhabit caves, overhangs, vertical walls; species that live in the interstices of the reef framework; and species found at depths greater than 50 meters. Specimens were identified by Janie Wulff and Timothy Swain of Florida State University using a combination of digital photography, field observations, and microscopic examination of siliceous spicules. Genera are organized into higher taxa according to Systema Porifera, Hooper & van …

Effects Associated With Dredging For Beach Renourishments On Reef Fish Communities Offshore Of Miami-Dade County, Florida:, Christian L. Avila

HCNSO Student Theses and Dissertations

Beach erosion is an ongoing problem in South Florida. Beach replenishment has been the primary means of maintaining these economically important beaches, and dredging offshore sand deposits, adjacent to reef tracts, has been the pervasive method since the 1970's. Over the past ten years, greater attention has been paid to potential impacts dredging can have on adjacent reef communities, which has led to increased monitoring efforts. With the increase in monitoring efforts, scope has expanded from a strict focus on the benthic community to include the fish communities. This study evaluates the effects of dredging on reef fish communities associated …

Effectiveness Of Asynchronous Reference Services For Distance Learning Students Within Florida's Community College System, Patricia C. Profeta

CCAC Theses and Dissertations

The impact of distance learning on higher education and the need to provide equitable library services to students in the digital environment emerged as critical areas during the 1990s. Library services available to distance learning students included digital reference and instructional services, remote access to online research tools, database and research tutorials, interlibrary loan, and document delivery. Digital reference services appeared to be one of the more significant services proffered by academic libraries although these services were developed often without forethought to goals and assessment. The purpose of this study was to examine the adequacy of asynchronous e-mail reference services …

Using Neural Networks To Develop A New Model To Screen Applicants For Apartment Rentals, Michael T. Furick

CCAC Theses and Dissertations

Credit scoring is a mathematical means of summarizing a consumer's credit and financial history into a three-digit number. This number provides an easy means of identifying and sorting consumer behavior into categories based on their financial history. To select applicants for loans and to set interest rates on loans, banks and financial institutions routinely use credit scoring. Auto insurance companies also use scoring to decide which consumers will be offered auto insurance and to set the price for auto insurance. Despite success in these two industries, scoring does not appear to be effective in the apartment rental industry in picking …

Information Policies And Practices Of Knowledge Management(Km) As Related To The Development Of The Global Aviation Information Network(Gain)- An Applied Case Study And Taxonomy Development, Jeffrey S. Forrest

CCAC Theses and Dissertations

The Global Aviation Information Network (GAIN) was initiated in response to U.S. Government policies seeking to reduce airline accidents. GAIN was to disseminate airline or aviation safety information in environments where public disclosure impedes the diffusion of information. Government legislation such as the U.S. Freedom of Information Act and other information policies create risks of public disclosure to those reporting information. Therefore, the problem investigated in this research was to identity and evaluate potential solutions to policy issues in public disclosure that prevent the collection and sharing of aviation safety information.

Interactions between GAIN, information policy, and knowledge management (KM) …
